摘要
传统谱相关分类法利用不同信号在α截面上所表现的不同谱相关特征可对通信信号进行分类,需要提取六种特征参数。文章结合小波分析法估计信号的码元宽度Ts,利用谱相关提取的三种特征参数,可对常见八类调制信号进识别。仿真表明,该方法具有很好的识别效果。
The traditional method of spectral correlation should get six characteristic parameters to classify communication signal. Three characteristic parameters with spectral correlation could used to identify eight kinds of common communication signals in this paper which is combined with code width get from wavelet transform. And simulation shows that this method is proper.
